ODO RL'E SS GASOLINE-HEATER.

SPECIFICATION forming part of Letters Patent No. 510,520, dated December12, 1893. Application filed November 12, 1892. Serial 110,451,756; (Nomodel.)

To all whom it may concern.-

Be it known that 1, WILLIAM E. ROBBINS, of Kansas City, Jackson county,Missouri, have invented certain new and useful Improvements in OdorlessGasoline-Heaters, of which the following is a full, clear, and exactdescription, reference beinghad to the accompanying drawings, forming apart hereof.

My invention relates toimprovements in heating drums or radiators,designed especially for use upon gas or oil stoves or burners, but whichmay also be applied to other types of heaters.

The objects of my invention are to produce a heating drum or radiatorfor the purpose of utilizing the maximum of heat derived from theproducts of combustion, to heat cold air, introduced from below and nearthe floor, into the interior of the drum or radiator, and radiating fromthe upper end thereof, throughout the room, and also to conduct theproducts of combustion, entirelyseparated from the heated air, to theflue or chimney, thus preventing the offensive odor and smoke from theburning oil or vapor, escaping from the heater into the room.

To the above purposes my invention consists in certain peculiar andnovel features of construction and arrangement, as will be hereinafterspecified and claimed.

In order that my invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawings, in which-Figure 1. represents a front elevation'of a gasoline stove with myheating drum or radiator applied thereto in operative position. Fig. 2.represents a horizontal sectional view, taken on the line2-2 of Fig. 1.Fig. 3.'represents a vertical transverse. sectional view of the stoveand drum, taken on the line 3-3 of Fig. 2. Fig. 4. represents a planview of the base or bottom plate of the inner cylinder of the drum.

1 designates a gasoline stove, comprising the cylindrical body portion2, supported upon suitable legs 3; the body portion being provided withapertures or slots 4, to admit air to the burners, 5, in the usual orany preferred manner.

tank 7, said pipe being also provided with or opening.

These burners are connected" through the medium of the pipe 6, to theoil' the usual valve to cut off or supply the burners with oil. A door8, is also provided in the body-portion of the stove, to give access tothe.

interior thereof.

Thedrum or radiator 9, consists of an annular casting 10, which isprovided with the annular shoulder or flange 11, depending from itsunder side, which shoulder or flange is provided with the annular grooveor recess 12, into which fits the upper end of the cylindricalbody-portion of the stove. The upper side of the casting 10 is alsoprovided with an annular groove or recess 13, and the inner margin ofthe casting is provided with theinwardly extending ears or lugs 14,diametrically opposite to each other, and each provided with avertically extending aperture The body-portion 15 of the drum orradiatoris of cylindrical form, and its lower end is inserted in the annulargroove or recess 13 of the casting. A top casting 16 is also of circularform, and is provided with a depending annular shoulder 17, having agroove or recess 18 therein, which fits upon the upper end of thecylindrical body-portion 15 of the drum. The upper casting is furtherprovided near its inner margin, and in its under side, with an annulargroove 19, ar-

ranged concentrically to the groove 18, near the outer margin of saidcastingg'and is also provided with an upwardly extending annu- I larshoulder 20, at its inner margin. A cylinder 21, vertically andconcentrically arranged within the bodyportion 15, has its upper endfitted into the inner groove 19 of the top casting 16, and has its lowerend proj eating a suitable distance below the lower end of the bodyportion 15, and resting upon a base or supporting plate 22 which isprovided with the diametrically opposite ears 23, in vertical alignmentwith and below the inwardly projecting cars 14 of the lower easting 10.These ears are provided with the notches or recesses 24. into whichengage the lower ends of tie-bolts or rods 25, which extend verticallydownward through the upper casting 16, ears 14 of lower casting and ears23 of supporting plate 22, being provided with a head at its upper endresting or bearing upon the top casting, and its lower end with screwthreads, engaged .by retaining nuts 26- which bear against the lowerside of plate 22. The plate is further provided with a raised surface27, circular in plan View which is adapted to fit closely the innermargin of the lower end of cylinder 21. It is to be understood thatacircular flange or segmental flanges may also be used if desired toprevent any movemerit of the lower end of the cylinder 2]. A cap orcover 28 also of circular form rests upon the upper side of the topcasting 16, closely inclosing the upwardly extending and annular flangeor shoulder thereof, and the cap or cover 28 is also provided withapertures 29 of ornamental configuration. The cap or cover is furtherprovided with a central opening 30, through which vertically projects adue pipe 31, one end of which is adapted to connect with the chimney orhouse fine, and the other end projects downward a short distance withinthe upper end of the inner cylinder 21 and engages the upper end of ashort chamber or pipe 32, the opposite or lower end of which is closed.Radiating pipes 33 communicate with the interior of this chamher andalso with the space between the outer and inner cylinders and 21. Thecylinders 15 and 21 are provided near their lower ends with radiallyaligned openings through which is inserted one end of an I shaped pipe34:. The inner end of this pipe communicates with the interior ofcylinder2l, and the lower end rests upon the floor, being provided withthe notch or recess 35 to admit air withinthe plpe.

From the above description, it will be seen, that the heat and productsof combustion from the burner, first impinge upon the under side orsurface of the supporting plate 22 which becomes highly heated, and arethen deflected into the space between the outer and inner cylinders,thus thoroughly heating the same, and enter the radially arranged pipesnear the upper end of the inner cylinder 21, and flow into the chamberor pipe 32 and escape thence through flue pipe to the chimney. At thesame time cold air enters the pipe 34 near its lower end and passes intothe interior of the inner cylinder 21 and then becomes heated and risesand escapes through the apertured cap, and radiates throughout the room.

From-the above description it will be seen that I have produced a cheapand efficient heating drum, and which can be applied conveniently to agreat variety of stoves.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A heating drum or radiator, comprising an outer cylindricalbody-portion, andaan inner cylindrical body-portion, having a supportingbase or bottom plate 22 provided'with notched radial ears .23, anannular top casting 16'c0nmeeting the upper ends of the cylinders, andan annular casting 10 engaging the lower end of the outer cylinder, andhaving inwardly extending cars 14: provided with apertures, andtie-bolts 25 extending through the top-casting 16, the cars 14 of thelower casting, and the notches in the cars. 23 of the supporting baseplate, and nuts engaging the projecting ends of the tie-rods,substantially asset forth.

In testimony whereof I affix my signature in the presence of twowitnesses.
